IMPROVEMENT IN VENEER-BOX MACHINES.

Specification forming part of Letters Patent No. 212,264, dated February11, 1879 application filed July 2, 1878.

To all whom it may concern- Be it known that I, ADOLPH B. Bron, ofBrooklyn, Kings county, State of New York, have invented certain new anduseful Improvements in Veneer-Box Machines; and I hereby declare thesame to be fully, clearly, and exactly described as follows, referencebeing had to the accompanying drawings, in which- Figure 1 is a frontelevation of the device; Fig. 2, a plan view of the same, and Fig. 3 aside elevation of the clamp for securing the joint of the box.

This invention relates to that class of machines in use for formingboxes of thin sheet material-such as wood, veneering, or pasteboardbutis especially designed and adapted for the manufacture of a particularvariety of box invented by me, and for which I have filed an applicationfor Letters Patent.

Inasmuch as the machine which forms the subject of the present inventionis adapted for forming any variety of box of the same class, furtherreference here to the particular DOX invented by me is unnecessary.

In the accompanying drawings, A represents a table, suitably supportedon legs, and having at one side a plate, B, firmly secured in a verticalposition. The plate B is provided with guides c c c 0, within which bars0 O are adapted to slide. To the bars O are secured, by means of screwsor bolts to, arms a a, which project through a slot in the table, asshown. Springs 9 g, attached at one end to the frame of the table and atthe other to pins upon the bars 0, serve to retract the latter.

A brace, 6, provided with a pivot at z, is firmly secured to the bed ofthe table, and supports a pair of curved levers, b b, which are adaptedto engage with pins 1) upon the bars 0. To the opposite ends of thelevers are pivoted bars (Z d, which are attached by means of a link, (1,to the treadle D, which latter is pivoted to a suitable cross-piece atthe rear of the table.

A T-shaped metallic piece, I, is let into the upper side of the table,and supports the mechanism proper for forming the box.

A form, H, which may be of any desired shape, is constructed in sectionspivoted together at h, and normally drawn together by means of a spring,h.

Pins m (shown in dotted lines) are inserted in the under side of thesections of the form, and travel in slots curved to the arc of a circledescribed about the pivot as the form is opened and closed.

Between the sections is mounted a rod, G, oval or cam shaped in crosssection, and adapted to open the form upon being rotated through themedium of the handle E and intermediate connections. (Shown in dottedlines.)

A sheet of metal, F, is provided with alug, k, fitted in a slot in thepiece I, and with bearings ff at either end, against which latter theactuating-arms a a press in the act of forming the box.

L is a rest for the clamp N, (shown in Fig. 3,) which consists of a pairof jaws, n a, the latter being faced with rubber a, pivoted together asshown. One of the arms of the clamp is provided with a link, 0, which isadapted to enter a slot in the other, when the jaws may be pressedstrongly together upon rotating the cam 0 by means of the handle 0.

The operation of the device is as follows: A suitable material forforming the box being chosen, a strip, V, is cut therefrom of a widthequal to the desired depth of the box, and of a length slightly greaterthan its proposed circumference. Glue is applied to one or both ends ofthe strip, in the usual manner, and it is placed around the form H, andbetween it and the sheet F, the form being first opened by means of thecam G. The joint of the box is brought in front between the arms a, aand over the slot in the table. The bottom of the box is cut or punchedfrom a sheet of any de sired material, and glue being applied to itsedge it is laid upon the form H.

The treadle D is next depressed, whereby the arms a a are caused toapproach each other, the intermediate connections operating in a mannerwhich will have been made evi* dent from the foregoing description oftheir construction. .As the arms a a come together, the strip V ispressed closely against the form H, the pressure being evenlydistributed from the metallic strip F. The arm n of the clamp N is nextinserted through the slot in the front of the table and brought behindthe overlapping ends of the strip V. Thejaws a n, being then broughttogether, are secured by means of the cam 0, the rubber a exerting astrong and even pressure upon the joint. The latter bein g thus secured,the treadle is released, when the arms a a separate and the strip Fopens.

Upon rotating the rod G, the form I-I contracts and the box is removedby means of the clamp N and set aside to dry.

While in the accompanying drawings I have illustrated the form ascircular in crosssection, it may obviously be of any desired shape.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. The process herein described ofmanufacturing veneer boxes, the same consisting in stamping or cutting asheet of wood to shape to form the bottom of the box, gluing the edgesof the bottom, and drawing the wallstrip around it and a form ofslightlyless diameter than the bottom, and clamping the glued edges ofthe wall-strip, whereby the bottom is secured under compression andsimultaneously with the formation of the walls of the box, substantiallyas set forth.

' 2. In combination with the metallic strip F, the form H, constructedin sections, and mechanism for causing the latter to separate,substantially as described.

3. In combination with the form H and strip 1 having end pieces, f, thearms a, bars (3, levers b, and treadle D, substantially as described.

4. In combination with the form H and strip F, the clamp N,substantially as described.
